Recent development in the application of alternative sterilization technologies to prepared dishes: A review 总被引:1,自引:0,他引:1
Sterilization is one of the most effective food preservation methods. Conventional thermal sterilization commonly used in food industry usually causes the deterioration of food quality. Flavor, aroma, and texture, among other attributes, are significantly affected by thermal sterilization. However, demands of consumers for nutritious and safe dishes with a minimum change in their original textural and sensory properties are growing rapidly. In order to meet these demands, new approaches have been explored in the last few years to extend the shelf-life of dishes. This review discusses advantages and disadvantages of currently available physical sterilization technologies, including irradiation (eg. Gamma rays, X-rays, e-beams), microwave and radio frequency when used in prepared dishes. The preservation effect of these technologies on prepared dishes are normally evaluated by microbiological and sensory analyses. 相似文献

Formation of highly resistant spores is a concern for the safety of low‐acid foods as they are a perfect vehicle for food spoilage and/or human infection. For spore inactivation, the strategy usually applied in the food industry is the intensification of traditional preservation methods to sterilization levels, which is often accompanied by decreases of nutritional and sensory properties. In order to overcome these unwanted side effects in food products, novel and emerging sterilization technologies are being developed, such as pressure‐assisted thermal sterilization, high‐pressure carbon dioxide, high‐pressure homogenization, and cold plasma. In this review, the application of these emergent technologies is discussed, in order to understand the effects on bacterial spores and their inactivation and thus ensure food safety of low‐acid foods. In general, the application of these novel technologies for inactivating spores is showing promising results. However, it is important to note that each technique has specific features that can be more suitable for a particular type of product. Thus, the most appropriate sterilization method for each product (and target microorganisms) should be assessed and carefully selected. 相似文献

本论文以平板型罐头食品为研究对象,探讨热杀菌过程中心部分杀菌值的简单计算方法。通常推算杀菌值就需要对温度的数值进行积分,或利用计算机软件来进行计算分析,比较困难和复杂。本研究首先利用数学解析计算出中心温度,再利用积分方法计算出杀菌值后,建立中心温度和杀菌值的函数关系式。通过函数关系式来推算杀菌值,比较简单易行。表达式以杀菌温度和Z值作为参数,推导出不同杀菌温度和Z值时杀菌值的表达式关系,不通过积分就可以通过简单的函数式来表达。将通过函数表达式求得的杀菌值和通过积分求得的杀菌值进行比较的结果表明误差在1 min以内,实现了杀菌值的简便计算。此方法便简单易行。有利于杀菌工艺的优化,对罐头食品的品质管理具有重要意义。 相似文献
